This is my 4th bottle and after almost 6 months I’m finally seeing some new hair growing. It’s not oily and the scent is very nice leaving my hair wavy. I make sure to use it everyday at night only. Have tried using on dry hair but wet hair is preferable.

Two weeks in and I'm already noticing a difference
[This review was collected as part of a promotion.] I've used this for two weeks, along with the Genesis shampoo/conditioner, and I'm already noticing a huge difference. I'm not seeing as much hair fall when I shower or brush my hair, and while I can't see a difference yet, my hair definitely feels fuller at the roots. This serum also doesn't leave me greasy, and I can still go a few days between washes while using this nightly. Only negative comment would be the cost - but the bottle is large and it seems that it will last a long time using one dose a day.

Smells great and I have noticed a difference.
I’m so happy I found this product. I use it every night, I apply one measured dropper, as I have somewhat thin hair. I massage it in for a few minutes then I follow it with other Kérastase products. The smell is divine. I wish they had a perfume hair spray of that smell. I have seen some hair grow over the last 3 months that I have been using it. I highly recommend this pro and will continue to use it every night.

Hi there! Thank you for your honest feedback on Genesis Serum Fortifiant. We're truly sorry to hear it didn't meet your expectations and that you found it to be greasy. We suggest applying up to 4 doses (1 dose = 1 pipette until the mark), section by section on dry or towel dried hair for best results. We recommend trying a smaller amount of product applied directly to the scalp areas where you notice less density, perhaps before bed, to minimize greasiness. To maximize your results, combine this product with the full Genesis range. https://tinyurl.com/yjutaqcc

From balding to hair down my back
[This review was collected as part of a promotion.] Genesis single handedly saved my hair. I had a thyroid issue and lost my hair quite a bit to shedding right around the time my salon brought in Kerastase and now my hair is down my back and amazing and it’s no exaggeration that I get stopped every time I am in public about my hair. I do have a great colorist, but the quality of my hair is amazing. I went from having bald spots and thinning to now having long hair that is vibrant and healthy. Absolutely worth the investment into me.

New growth with daily use! Bought a backup bottle
Kerastase is quickly becoming my favorite hair care brand — this was one of my first purchases after trying a billion different products and not getting consistent results.
I love how gentle and non- stimulating this feels going onto the scalp. Some growth serums have a tingle that doesn’t feel gentle enough for my scalp, creating heat and just making my hair feel a bit sticky.
This feels like water, absorbs without residue and is so easy to use! Been about 3-4 weeks and I have a bunch of baby hairs (new growth because it’s the color of my root and extra soft) — loving the results

I like it, didn’t blow me away
I have a little bit of hair loss and this serum hasn’t done a lot for growth and scalp but it does make my hair feel healthy

Must Have
This product to make such an incredible difference in my hair in my husband’s hair as well as someone who had started thinning. Also had someone with severe anemia, and my hair was falling out crazy and now when I brush my hair since I started using this, I see far less hair follicles in the brush so this product is definitely. this will be my second bottle.

Seeing results already
Love the smell, noticed a lot let fall out/shedding of my hair, but putting it on at night did cause me to have to restyle my hair in the morning - typically with heat - which feels counter intuitive because it would leave a slight residue and cause my hair to curl/texture when I woke up. i'm expecting only better results as I continue to use it - only one month in so far!

Some improvement
I purchased this for my daughter and myself who have both been experiencing hair loss, possibly due to some extreme recent stress. We used it for around 8 weeks. I did notice less hair fall and some regrowth for my daughter over the course of this time. As for myself, I have not seen much of a change. My daughter will continue to use it until the bottle runs out. After that we will try the initialiste serum.

GROWING AND GLOWING
My hair has never been so healthy since I started this product. My hair is growing like crazy! It’s shiny and softer than ever! I use it after I wash my hair once a week while it is still damp. I comb my hair out and fill the vile that it comes with and put it down the middle of my part. I flip my head over and put it along my base hairline and just start rubbing it in. I let my hair air dry and I do not blow dry it anymore. I have never received more compliments on my hair!

Smells divine
[This review was collected as part of a promotion.] I do like this product however it does make my hair dry and crunchy. I have to break the cast by combing it out after it dries. It uncrunches very easily with a quick comb thru.
